Earlier quoted context omitted.
I have a Samsung fridge. It’s not a smart fridge, it doesn’t have a screen, bluetooth, or any way to connect to it. I logged into my UniFi stack to monitor devices and it showed up. It had gotten the connection details from my wife’s phone, the other Samsung device and was transmitting data back to Google and Samsung.
What model of fridge?! How did you know the random device on your network was your non-smart fridge? This is a wild story. I want to believe but if it's true I think there's no sane solution other than exploratory surgery on every appliance you buy.
So I went digging in UniFi, found it, and blocked it. Same with my HP Printer that sent almost a gig of data to Google Print Services daily.
